1. Product Overview

3M™ Extreme Sealing Tape 4411N is a translucent, single-sided, pressure-sensitive acrylic adhesive tape reinforced with a tough ionomer backing. At 1.0 mm thickness, it conforms effortlessly over rivets, screw heads, seams, joints, and gaps, creating a reliable watertight seal. The clear, paintable film provides excellent abrasion resistance and outdoor durability, making it a versatile solution for demanding sealing applications. Unlike liquid sealants, it delivers an instant, non-oozing bond, reducing downtime and ensuring immediate protection against water intrusion while maintaining flexibility and long-lasting performance.


2. Applications

  • Truck and trailer roof sealing

  • Window and door sealing

  • HVAC joints and seams

  • Gutter protection

  • Overlapping panels in construction and transportation
